Any photos of the reinforcement? I'm building mine (kit) and have been putting small strips of CF flats embedded in the foam where (I think) the weak points are. I may end up glassing the area once I get the fuse halves together.

Ya... they are in this thread... but im going to start a new thread just for what I have done... Ill post it here when its started...

The whole capacitor plugged into the receiver thing started with the car guys running foam tires on carpeting indoors. They would build up static electricity that the capacitor would supposedly act as a surge volume in case the static electricity would somehow jump over into the controls.

For planes I can't think of a scenario where a capacitor would really help. If the voltage regulator in an ESC developed a dead short a small cap is not going to absorb the entire battery load.

Some servos can create really big current spikes when they're stalled. This can in some cases cause a brownout which can be enough for a receiver to fail. Because of this, and nothing about cars, is the reason for caps on the tslrs TX600+ reciever.

Who talked about absorbing a battery load? The cap is there to keep the voltage up in those very short current spikes that can, and has, caused brownouts in some receivers.

The diversity of opinions makes this a fun hobby. I would rather fly with 2 battery packs than a battery and a capacitor. If capacitors do decide to discharge all at once they can put out a pretty large pulse that I don't care to subject my receivers to. If you have older radio gear that needs 2-3 seconds for the rx to reboot just about anything is worth a try. The modern rx's reboot in milliseconds.
